We look at the division of 35401663 by 522 
The aim is to understand the frequency of 522 in 35401663.

Advancing to step 1:
When dividing 3 by 522, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 522

On to step 2:
When dividing 35 by 522, we get 0 with a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Include the next digit (4) from the dividend after 35, then repeat: 354 / 522

Moving on to step 3:
354 divided by 522 is 0 with a remainder of 354.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 354, we end up with 354.
Append the next digit (0) from the dividend to 354 and continue with: 3540 / 522

On to step 4:
522 goes into 3540 6 times with a remainder of 408.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 3132 from 3540 leaves us with 408.
Include the next digit (1) from the dividend after 408, then repeat: 4081 / 522

Let's proceed to step 5:
522 goes into 4081 7 times with a remainder of 427.
The next digit of our result is 7. 
Result so far: 67.0
If we subtract 3654 from 4081, we get 427.
Take the next digit (6) from the dividend and append it to 427, then repeat: 4276 / 522

Advancing to step 6:
When dividing 4276 by 522, we get 8 with a remainder of 100.
Put 8 as the next digit of the answer. 
Result so far: 678.0
If we subtract 4176 from 4276, we get 100.
Bring next digit (6) of the dividend behind the 100 and repeat the process: 1006 / 522

Advancing to step 7:
The number 522 fits into 1006 1 times, leaving a remainder of 484.
Put 1 as the next digit of the answer. 
Result so far: 6781.0
If we subtract 522 from 1006, we get 484.
Fetch the next digit (3) from the dividend, attach it to 484 and continue: 4843 / 522

Let's proceed to step 8:
522 can be fit into 4843 9 times, resulting in a remainder of 145.
The number 9 becomes the next digit in our result. 
Result so far: 67819.0
The remainder is 145 after subtracting 4698 from 4843.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Advancing to step 9:
522 can be fit into 1450 2 times, resulting in a remainder of 406.
Put 2 as the next digit of the answer. 
Result so far: 67819.2
Subtracting 1044 from 1450 leaves us with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Going ahead to step 10:
522 goes into 4060 7 times with a remainder of 406.
The next digit of our result is 7. 
Result so far: 67819.27
The remainder is 406 after subtracting 3654 from 4060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Going ahead to step 11:
If we divide 4060 by 522, we get 7 and a remainder of 406.
Record the quotient 7 as the next digit in the result. 
Result so far: 67819.277
Subtract 3654 from 4060 to get 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

The final result is 67819.277 with a remainder of 0.0406.
